Features

• The Sidchrome 440 Pro Series
• This range is a premium collection of tools and accessories with sleek design, highest quality materials, comfort and ultimate durability. The 440 Pro Series is created for people who want a superior, high-performing product that can be relied on for years to come.
• Better grip, comfort and ease of use
• The distinguishing feature of the 440 Pro Series ring and open-ended spanners is the distinctive scalloped shaft, delivering improved ergonomic grip with a logical place for your thumb to rest for increased torque. The scallops not only increase comfort and ease of use, but make the tool both lighter and stronger, making it ideal for repeated daily use, to relieve pressure on hard-working hand muscles and joints.
• Get increased strength and more torque, because the tensioning load is spread over a larger surface area. Plus the new ring design places one ring parallel to the shank, allowing you to locate on a smaller section of the fastener.
• Anti-slip grip
• In a tight-fitting situation, any minimal improvement on access and maneuverability is a win. Each 440 Pro Series open-ended spanner has a small groove, which works as an anti-slip mechanism that improves grip and reduces the chance of your hand giving way, damaging the bolt.
• Torque plus for better angles and maneuverability
• The ring spanners have wavy, curved groves that allow for better grip and purchase on bolts. This is good for stubborn bolts that have been rusted on, painted over or simply stuck on for years, making them difficult to budge. The innovative Torque Plus scalloped grooves on the ring spanner allow for improved purchase on the bolt, because contact is concentrated to the flats of the fastener, not the corners.
• Made from the highest quality alloys
• Each spanner in the 440 Pro Series is made from chrome vanadium, alloys that provide the necessary strength and hardness to get the job done. Using the Hardness Rockwell C-Test, the 440 Series rates in the 50-65 scale, meaning they have the necessary hardness to be durable, reliable and strong enough to tackle even the most stubborn bolts. The chrome plating on the Sidchrome 440 Series ensures each spanner is durable, cleanable and rust proof.
